An arrangement for controlling the height above or depth below an irregular surface of a body moving over or below the surface includes a rotation sensor coupled to a controller responsive to an angular deflection signal output by the rotation sensor. The rotation sensor and controller are mounted to a vehicle moving over the surface such as an agricultural vehicle traversing a field. A semi-rigid, flexible arm has a first end coupled to the rotation sensor with a ground engaging member attached to a second opposed end of the arm. In one embodiment, the flexible arm includes an elongated coil spring attached to a rigid shaft and the ground engaging member is a spherical ball attached to the shaft's distal end. The coil spring is pre-loaded to a selected bending or flexure force and permits the ground engaging member to impact obstructions in the field without damage to the rotation sensor. The coil spring also prevents damage to the rotation sensor when the vehicle is reversed in direction. The flexible arm may be urged downwardly to ensure that the ground engaging member contacts the soil and upward and downward rotation stops may be provided to limit rotation of the rotation sensor and flexible arm combination. When a plurality of rotation sensors and flexible arms are employed such as along the length of a combine header, each rotation sensor may be individually calibrated by rotating the sensor relative to the head unit to which it is mounted to permit all sensors to uniformly measure the height above or depth below the soil surface.

The invention is a combination of a short ground sensor arm mounted close to the cutter bar and a longer rod mounted towards the rear of the header. The short front sensor and long rear sensor are connected by a linkage which translates motions from either sensor to the other sensor. A second linkage translates the motions of both sensors rearward to a protected area under the header which contains the potentiometer. This configuration transmits useful ground position signals to the header height controller in both low and high cutting heights. The invention advantageously reduces the likelihood of damage to the short front sensor when the machine is reversed since the longer rear sensor arm pulls the shorter forward sensor arm up by means of the linkage to a position where damage is unlikely.
